Definitions
- the present invention relates to a body structure of a rear part of a motor vehicle.
- the invention also relates to a motor vehicle equipped with a body structure of this type.
- the invention is based on the general concept of connecting individual components of a body structure of a rear part of a motor vehicle to one another not only, for example, via a cohesive material joint but in addition via a form-fitting connection.
- the body structure according to the invention has at least two side walls, each having a side wall element, and a bulkhead with a cross member on the ground side.
- the cross member is provided, at each longitudinal end, with rearwardly open mounts into which a front end region of the respective side wall element is pushed and, as a result, held in a form-fitting manner.
- the respective side wall element is connected to the cross member in this case in the region of the mount, which is of a shoe-like configuration, via a welded joint and/or a riveted joint.
- the mounts provided, according to the invention, on the cross member also make it easier to assemble the body structure, since they already enable the side wall elements to be prefixed or oriented relative to the cross member by the side wall elements being pushed into the mount of a shoe-like configuration on the cross member. If the respective side wall element is positioned in the cross member in such a manner, it can be connected thereto in this region by a suitable connecting process, in particular by a welding or riveting process.
- the body structure according to the invention therefore provides a simplified possibility of assembly and, in addition to a purely cohesive material joint, also a form-fitting connection between the individual components of the body structure, thus improving the introduction of force and transmission of force between the individual components, which is of great significance in particular in the event of a crash.
- the cross member and the two side wall elements are formed from a light metal diecasting.
- a light metal diecasting aluminum is suitable as a possible material for the light metal diecasting, aluminum being both light and corrosion-resistant, which is likewise highly advantageous in motor vehicle manufacturing and in particular in sports car manufacturing.
- a cross member and side wall elements configured in such a manner it is possible to produce them cost-effectively and with a high degree of dimensional accuracy, thus enabling a favorable, but at the same time high-quality manufacturing.
- the cross member and the side wall elements are connected to one another via self-piercing rivets.
- pre-drilling is not required for the self-piercing riveting process according to the invention, as a result of which the process can be used comparatively economically.
- riveting processes provide a fixed, nonreleasable connection which, for example in comparison to screw connections, customarily also does not exhibit any weakening of the connecting force in the long term.
- FIG. 1 is a diagrammatic, perspective view of a body structure according to the invention in a region of a connection of a side wall element to a cross member;
- FIG. 2 is a diagrammatic, partially sectioned view of the body structure according to FIG. 1 .
- FIG. 1 there is shown a body structure 1 according to the invention that has a bulkhead 2 which runs substantially in a transverse direction of a vehicle and customarily separates a passenger compartment from a rear space located there behind in a direction of travel, in particular an engine compartment.
- the bulkhead 2 is connected at its lower edge region to a cross member 3 which, for its part, is connected at each of its longitudinal ends to a side wall element 4 .
- a cohesive material joint for example a welded joint, between the side wall element 4 and the cross member 3 , and, of course, other types of connection, such as, for example, adhesive bonding or riveting, are conceivable.
- the cross member 3 is provided with rearwardly open mounts 5 into which a front end region of the respective side wall element 4 is pushed and is welded and/or riveted to the cross member 3 .
- the cross member 3 therefore has, at each longitudinal end, a mount 5 in which the front end region of the side wall element arranged in each case on this side engages.
- the cross member 3 and the two side wall elements 4 are preferably formed from a light metal diecasting, in particular from diecast aluminum, and each have numerous stiffening contours 6 , in particular reinforcing ribs, with which the respective component is reinforced in order to absorb corresponding loads.
- the stiffening contours 6 can be defined in advance with regard to their position, their orientation and their strength, for example by a relevant calculation program, in particular by a “finite-element program”, such that they are arranged only at those points at which they are actually required because of the loads which occur there.
- a relevant calculation program in particular by a “finite-element program”
- the two side wall elements 4 are in contact with corresponding wall sections of the cross member 3 preferably only in some regions in the respective, associated mount 5 of the cross member 3 , as a result of which an at least small relative movement between the two components 3 and 4 is still possible, but a reliable transmission of force can be ensured.
- the side wall elements 4 and the cross member 3 can be connected, for example, via self-piercing rivets or via an adhesive bond, and also via a cohesive material joint already mentioned above, for example by welding.
- the mounts 5 provided, according to the invention, on the cross member 3 , a good transmission of force between the side wall elements 4 and the cross member 3 can be achieved, which has a positive effect in particular in the event of a crash, and, furthermore, the assembly of the body structure 1 can also be simplified, since the side wall elements 4 can already be prepositioned or prealigned with respect to the cross member 3 by the front end regions of the side wall elements 4 being inserted into the associated mounts 5 on the cross member 3 .
- the connection which is pre-aligned in such a manner, between the cross member 3 and the side wall elements 4 is fixed only in a subsequent manufacturing step by a relevant connecting process, for example adhesive bonding or welding.
